Arsenal are at risk of not qualifying for Europe's premier competition for the first time in 14 seasons but Wenger was cryptic when it was suggested that a rumoured £1.5 billion takeover could end their current slide.

"If people are ready to invest money that means the club does not go too much in a bad direction," he said.

Bale and Lennon were both allowed to run behind the Arsenal back line and advance on Wojciech Szczesny as they grabbed quickfire goals and Wenger admitted that his side's defending did not look good on first glance.

"I will have to watch [the defending] again but it looks a bit like that," he conceded when asked if their poor defensive display had proved costly.

"It's difficult to swallow a defeat like that because of the effort we put in and because the energy levels we produced for the 90 minutes was tremendous.

"But we made it difficult for ourselves in the first half. We had no shots on goal, we were 2-0 down.

"In the second half we came back and dominated the game but there were many fouls that intelligently stopped the game and it was difficult to get a flow in the final 20 minutes.

"The game suffered from too many stops in play and we didn't find the second goal."

Wenger refuted claims, however, that the balance in power in north London was shifting after Spurs' latest victory.

"Look, that's not the impression I get from the game today," he insisted.
